the PI swap is pretty common and will raise your compression to a number i forget >_< YOu can get 370cfm heads for $900 thats getting close to as good as 4v
your car is a 98 so it still might qualify for a Intake pi swap from the dealership, the recal was on cars that where so old. I think my 97 wa sone year shy of getting the recal.

Nitrous will be the cheapest mod. That should put you in 12`s in the 1/4 easily if you can drive. To convert to 4v heads, your talking lots of cash. It can be done but it`s not worth the $$$.

You have 3 choices...
1) Take your stock heads to Renegade Racing for the best flowing NPI's available with a SVO/FRPP Intake
2) Get PI heads (99-04) GT heads and intake (can have them ported also)
3) Get SVO/FRPP heads and intake (very expensive but worth the money)
All of these will add a minimum of 50hp to your car.
Cams are also a very big addition. Most will add 30 +rwhp
